This tutorial lays the foundation to participate in the Students' Cloud Observations Online (S'COOL) project. S'COOL engages students in making and reporting ground truth observations of clouds then comparing those observations with data from the...(View More) CERES satellite instrument. Student observations are taken within +/- 15 minutes of the satellite overpass schedule; scientists then use those observations to validate and improve the satellite results. The tutorial covers the following four topics: determining satellite overpass time, observing cloud properties, transmitting results to NASA, and comparing results with satellite-retrieved properties.(View Less)
